How Can I Disable a Vehicle Tracker?

Vehicle trackers are disabled by emitting radio waves that block the ability of signals to travel between the GPS tracker and satellites, called jamming; by spoofing, which is emitting erroneous signals to be confused with the signals sent by the tracker; and by blocking wireless signals. A vehicle tracker can also be disabled by covering it with metal.

Disabling a GPS tracker is as simple as installing a signal jammer in the cigarette lighter port of a car. It acts as a shield that extends 30 feet out from the car by emitting signals that confuse the GPS, making the car invisible to the satellite. However, GPS jammers are illegal to sell or own in some countries because they interfere with legitimate GPS signals nearby, such as those in other cars, airplanes and even those used by the military.

GPS spoofing involves emitting signals that the satellite picks up, which leads it to believe the vehicle is in a different location. Vehicle trackers that use wireless signals to send updates to the satellite can be disabled by using a cellphone blocker. Most tracking devices are hidden, but if they are found, they can be covered with metal, which blocks signals to and from the device.
